Bullinger’s The Old Faith (1537) as a Theological Tract

The Swiss Reformer Heinrich Bullinger wrote The Old Faith (1537) to be read alongside his treatise on the covenant, De testamento (1534). His aim was to convince a wide audience that the Reformed faith was in conformity with a correct reading and interpretation of the biblical message and the church fathers. The work displays insight into key biblical and theological themes and, as with Irenaeus’s The Demonstration, has apologetical, catechetical, and polemical purposes. We can learn with Bullinger to read and exegete the text of the biblical canon and learn from faithful exegetes of the past.
